What does being committed to your marriage really mean? UCLA psychologists answer this question in a new study based on their analysis of 172 married couples over the first 11 years of marriage.

"When people say, 'I'm committed to my relationship,' they can mean two things," said study co-author Benjamin Karney, a professor of psychology and co-director of the Relationship Institute at UCLA. "One thing they can mean is, 'I really like this relationship and want it to continue.' However, commitment is more than just that."
